Did Runningman say Unitarians cannot pray to Jesus? I seem to recall he said the Bible says nobody prayed to Jesus.
Not sure if he specifically said for them not to, but he did affirm that it is a "false doctrine" that Jesus is prayed to in Acts 1:24.

John Schoenheit affirms Jesus is prayed to there:
“You, Lord.” The evidence shows that this prayer is to Jesus, not to the Father.
